Gmock can't mock method parameter with both operator bool() and operator int() methods implemented

[GoogleCodeExporter]

What steps will reproduce the problem?
1. take a class:
class ParClass {
public:
    operator int() const;
    operator bool() const;
}

2. now we want to mock a method accepting ParClass as on of the parameters

Than you get an error like this:

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

gmock_1_6_0, ubuntu 11.10

Please provide any additional information below.

Problem can be solved by implementing ostream << (ostream, ParClass), so 
actually issue is not big.

O-o-o-o-ps, it's not gmock, it's google mock... sorry... just close the issue :)
